Also called "Clash Man", I suspect due to translation issues between the Japanese confusion of the English 'L' and 'R'; this is the Game Boy version of Mega Man II's Crash Man. A pretty good song, even if it does sound like a bad anime for about ten seconds around two thirds of the way through. The original version also makes use of obnoxiously high octaves, which I've toned down here for piano. Enjoy.
